What are the applications of FRET-based pH sensors?

FRET-based pH biosensors have applications in monitoring water treatment processes like ion exchange, demineralization or reverse osmosis. They can detect the presence of hard water ions in treated water, allowing for the assessment of water treatment efficiency. They are also utilized in medical diagnostics and environmental surveillance. These sensors enable the detection of pH alterations in biological specimens like blood, urine, saliva as well as within cellular and tissue environments. They serve to track pH fluctuations associated with disease development and treatment responses. Moreover, FRET-based pH sensors play a crucial role in industrial settings such as facilitating pH monitoring during the food and beverage manufacturing process.
